Having done half a dozen V-USB tutorials I decided it’s time to whip up something cool. As USB keyboards were an area untouched, I decided to make a small USB HID keyboard device that types a password stored in EEPROM every time it’s attached. A new password can be generated just by tabbing CAPS LOCK a few times (4 times to start password regeneration and one tab for each password character generated, 10 is the default password length)

Using the Bus Pirate to read the SVP supervisor power on password off an IBM T30 Thinkpad: [via]
A friend of mine recently came upon an old IBM T30 Thinkpad at an auction for $40. Bringing it home, he found that there was a power-on supervisor password. This can’t be reset by removing the battery, as the pswd is stored on an EEPROM on the motherboard….. So it came to me!
I recently purchased a Bus Pirate v3 from Seeedstudio, and decided to give it a quick test run..

So you’ve got an old Toshiba Satellite (full list of compatible models at the bottom), turned it on and to your aggravation you are greeted with a Password prompt. While there are several ways to go about removing the password, I chose to build a very simple dongle device which connects to the parallel port – known in the trade as the Loopback Plug. When connected to the computer and the machine is started up, the BIOS will not prompt you to enter the password, allowing startup of the computer and removal of said password.

Probably everyone has a long list of passwords to remember. But are they safe from other and from forgetting them. Some people are using same password for all cases…well this is not safe. And of course using popular words as passwords also isn’t safe. It is better to use characters mixed with numbers. But these are hard to remember.
Alberto ricci bitti have built a fancy embedded pocket password reminder which can remember hundreds of passwords. The circuit is simple – menu navigation is done with encoder rotor and single button. Information from Cypress CY8C27443 microcontroller is displayed on 2×16 character LCD display.
